What two numbers multiply to -921 and add up to 920?

Here we answer the question: "What two numbers multiply to -921 and add up to 920?"

The answer to your question is:

-1 and 921

Below we illustrate and prove that -1 and 921 multiply to -921 and add up to 920:

-1 × 921 = -921
-1 + 921 = 920

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 920x - 921 = 0

If so, the solution to factor the quadratic equation above is:

(x - 1 ) (x + 921)

To summarize, since -1 and 921 multiply to -921 and add up 920, you know that the following is true:

x² + 920x - 921 = (x - 1 ) (x + 921)
